not for the foreseeable future from what ive heard, theres still a push on the .17 hornet trying to recoup some of the investment there, without introducing something with the potential to kill it plus cz seem to have their hands full with the new 557 line and it would take quite a bit of retooling to set up, I don't think its a matter of screwing a new barrel on your 455, looks like a savage or browning. I hope it does take of as it looks impressive,but there is no doubt the .17 market is just about saturated.

Well, Ruger discontinued the 77/17 which was your only other option (aside from a Volquartzen). If I were you and you are really liking this cartridge, it may not be a bad idea to stock up on the ammo. Your cartridge may be destined to go the way of the 5mm.

.17 Hornet gives you another 650+ fps and the ability to reload the cartridge. That is where I would spend my money.

the .17WSM isn't a bad cartridge, it just fits into a tough little void

price per round is well into centerfire (30-34 cents per round)

the length of the cartridge puts it into centerfire action range....but as was mentioned, it doesn't pack as much as the .17 Hornet (my personal favorite .17 CF cartridge).

most companies, CZ included, didn't feel the juice was worth the squeeze to re-engineer their rimfire lines to accommodate the WSM...or so I imagine. And I can't imagine too many CZ 527's in .17WSM selling next to a .17 Hornet...some, to be sure, but enough to make it worth engineering the magazines to work etc...I doubt it.

For me, the .17HMR reaches out to 200 yds pretty well. Beyond that, I go to CF (.223Rem).
